SHUTTER-CLOSER.

SPECIFICATION forming part of Letters Patent No. 556,110, dated March 10, 1896.

Application filed April 16, 1895. Serial No. 545,913. (No model.)

To @ZZ whom t may concern,.-

Be it known that l, CHARLES E. SMITH, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Shutter-Closers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in shutter-workers, and has for its object the production of a simple and practical device for operating a shutter from the inner side of the supporting-wall to which it is hinged; and to this end it consists in the construction and arrangement of the component parts of the shutter-worker, all as hereinafter more particularly described, and pointed out in the claim.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure l is a horizontal section of a portion of a supporting-wall or window-casing, a pair of shutters secured to said wall by hinges, shown by dotted lines, and shuttereworkers connected to open and close the shutters, one of the shutters being shown as closed by full lines and as partly open by dotted lines, and the other shutter being illustrated as partly open by full lines and as closed by doti edllines. Fig. 2 is an end elevation, partly in section, of the parts as shown at Fig. l, the hinges for the shutter being shown by full lines. Fig. 3 is a horizontal section showing a portion of the supporting-wall or window-casing and one of the shutters and its worker arranged in their positions assumed when the shutter is entirely open. Fig. 4 is a detail vertical section taken on line 4 4, Fig. l; and Fig. 5 is a detail vertical section taken on line 5 5, Fig. 1.

A is a supporting-wall or window-casing of any desirable form, size and con struction, and B B are shutters having their outer sides hinged to the wall A, as by hinges l). (Shown by dotted lines at Fig. l and full lines at Fig. 2.) These hinges form no part of my present invention, and consequently it is unnecessary to further illustrate or describe the same. The wall A is formed with apertures a extending therethrough in proximity to .the hinged sides of the shutters, and plates C D are secured to said wall and are formed with slots c d aligned with each other and the apertures a.. Each plate Gis secured to the wallA by suitable fastening means c. Its inner end is arranged within the outer end of the corresponding aperture d and its opposite end is provided with separated lugs or ears c2 which project beyond the outer face of the wall A. Each plate D is secured to the wall A by suitable fastening means d'. lts slot d is of less length than the slot c of the opposite plate C, and its outer or front face is provided with separated projecting lugs or ears d2 formed with perforations d3.

E E are actuating-bars arranged in the perforations c1, and the slots c d and having their inner ends provided with suitable hand-engaging pieces e and perforations e'. Suitable stops E are passed through the perforations cl3 e and hold the actuating-bars in their adjusted position.

Rocking levers F are arranged at the outer side of the wall A, and their intermediate portions are pivoted at f to the projecting lugs or ears c2. One extremity of each lever Fis pivoted at f to the outer end of the adjacent actuating-bar E, and the opposite extremity of said said lever is loosely connected to one end of a link G, having its opposite end pivoted to the adjacent shutter between its side edges by a staple g or other suitable device. The loose connection between the levers F and the links G may be effected by any suitable means, but the outer end of each link G is preferably formed with a lengthwise slot g and an engaging-pin g2 projecting across the slot, and the inner face of the adjacent lever F is provided with a loop f2, movable in the slot g and engaged with the pin g2. The pin g2 is of considerably less diameter than the distance between the inner faces of the opposite sides of the loop f2, and consequently the links G and the levers F are connected together by a lost motion. The end of each lever F, adjacent to the corresponding link G, is provided with an engaging end F, projecting beyond the loop f2 for engaging the outer -face of said link G and positively holding the same in its adjusted position.

When the shutter is either opened or closed IOO to its full extent, the link Gbears against the outside of the shutter its full length, and the end of the lever F bears directly against the outside of the link for about three-quarters of its length, and the lever and the link unite in bracing the shutter in its closed position.

As clearly seen at Figs. l and 8, the handpieces e of my improved shutter-workers are arranged in close proximity to the inner face of the wall A when the shutters are closed or open, and the stops E operate to securely hold the shutters in either position. lVhen partly opening one of the shutters B the cor responding stop E is withdrawn, the handpicce c is pulled outwardly from the wall A until the actuating-barL` is arranged at substantially right angles with the outer face of the wall A, as shown at Fig. l, and the stop E is then placed in its operative position. If it is desired to entirely open said shutter E, the hand-piece c is rocked away from the hand-piece of the opposite shutterworker and is again forced toward the inner face of the wall A, thus compelling the shutter to continue its outward movement until the parts assume the position indicated at Fig.

The operation of my invention will be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be particularly noted that in y improved device consists of a minimum number of parts, is readily operated, and positively holds the shutters in either their closed, partly open, or open positions.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

An endwise-moving bar provided with a series of perforations, extending through an aperture in the wall, and having a pivoted or swinging motion therein, perforated cars between which the inner end of the bar passes, and a stop-pin passing down through the ears and the bar, combined with a lever pivoted on the outer side of the wall,havin g its shorter end pivoted to the endwise-inoving bar, and provided upon one edge near its outer end with a loop, and a link, connected at one end to the shutter, and at the other to the loop, the outer end of the lever being made to overlap the link, substantially as shown.

In testimony whereof I have hereunto signed my naine, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 30th day of March, 1895.
